Hi Panusri,
All these requirement should be pre-highlight up-front before I send out samples, instead of request after I posted out. As I did not take photo of the samples, all are in plain foil & label with marker pen only. No artwork/ formal packaging.
Info on the pack is : Product name, Spec code (Sprint TH), Amount, and Date
Attached please find the Proforma invoice. There is no commercial invoice, we call it as proforma invoice, and is the same content as Packing list.
For the Product Bulletin/Ingredient, I will draft a simple documents with the list of ingredient.
